JAMES W. RUIVISEY, OF WEST BERKELEY, CALIFORNIA, ASSIGNOR-TO RUMSEY CAR- DOOR AND EQUIPMENT COMPANY, A CORPORATION OF ILLINOIS.

GAR-DOOR.

Application filed October 29, 1913.

To all whom it may concern:

Be it known that I JAMES W. RUMsEY, a

a citizen of the United States, and a resident of Vest Berkeley, county of Alameda, State of California, have invented certain new and useful Improvements in Car-Doors, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which Figure 1 is a front elevation of the lower part of a box car showing the lower part of the car door; Fig. 2 is a horizontal sectional view taken through the car door and adjacent structure on the line 2-2 of Fig. 1; and Fig. 3 is a vertical section on the line 3-3 of Fig. 1.

The object of this invention is to provide simple means for guiding the lower end of the door and at the same time stiifening. the door and also serving to seal the door against the car structure in its closed position, as more fully hereinafter set forth.

In the drawings, a designates the lower edge of the car door which is adapted to be hung in the usual manner to enable it to slide back and forth across the door opening. At the inner edge of the door is provided suitable means for receiving the inner edge of the door and'holding it against the car structure when the door is closed, the means shown in the present drawing consisting of a sheet steel post member 6. At the rear edge of the door there is provided means for bringing that edge of the door against the car structure and holding it tightly against the car structure, this means serving also as a weather strip. Inv the drawing I have shown that this may be accomplished by a sheet steel post member 0 and a metal strip d fastened on the inner face of the door.

These devices for sealing the door at its inner and outeredges when closed are covered by co-pending applications and I, therefore, do not claim. them specifically in this application.

Fastened against the car body below the edge of the door is a series of three or more guide brackets 6, each having an up-turned guiding lip f. Fastened to the lower edge of the door and extending the full length thereof is a metal plate h, this plate being Specification of Letters Patent.

Serial No. 798,017.

fastened to the inner face of the door and having its lower edge extending below the lower end of the door and turned outwardly under the lower edge of the door to form a longitudinal flange i, which closely abuts the lower edge of the door throughout the length thereof. This flange plate h is set into the door so as to be flush with the inner face of the door, and this insetting of this plate is accomplished preferably by making the lowest board j of the inner layer of the door of less thickness than the other boards of the inner layer. The lower edge of this thinner board j depends below the lower edges of the outer boards 75 of the door, so as to bring the flange 2' of the plate It down behind the upstanding lugs f of the guide brackets.

It will be seen that as the door is slid back and forth in its closing and opening operations, the lugs f will guide the door, and when the door is in closed position the middle one of these brackets is used as one member of a cam device for pushing the door bodily toward the car structure .and thus sealing the door after it is brought to closed position. To do this, the flange 2' is provided with a tapering outward projection Z about midway its length, which projection, when the door is slid to closed position, will impinge against the inner face of the middle upstanding lug f and crowd the door against the car structure, and thus tightly and securely seal the door. To permit the cam Z to pass the outer one of the lugs f in opening and closing, the middle lug f is placed closer to the car structure than the other two lugs, as shown in Fig. 2.

In addition to providing a sealing and guiding means for the door, it will be seen that the plate It and its flange 2' serve to stiffen the door across its entire width, and, in order to utilize this plate also as a sliding device, it is extended far enough upwardly on the inside of the door to strike against the threshold .plate m when the door is forced into sealing position.

Having thus described my invention, what I claim is In combination with a car body, of a hori- Zontally sliding door provided at its lower edge with an outwardly extending metal flange hose outer edge is formed into a cam When the door is closed, for the purpose cam, and a plurality of guide brackets fasset forth. 1.3 tened to the car body and having lugs eX- In testimony whereof I hereunto affix my tending upwardly infront of said cam, said signature in the presence of two Witnesses.
